Abstract
A fuel injector of diesel oil engine using multiple fuel is prepared as setting ring oil groove and lubricant oil channel connected through to ring oil groove on body of needle valve, connecting lubricant oil channel on body of fuel injector through to lubricant channel and ring oil groove on body of needle valve for improving lubricant and seal effect between needle valve on fuel injector and body of needle valve.
Description
Technical field
The present invention relates to a kind of diesel injector, more particularly relate to a kind of can dimethyl ether fuel, the diesel injector of pluralities of fuel such as methyl alcohol, ethanol.
Technical background
Diesel engine is the power of automobile, tractor, engineering machinery, naval vessel and train, and the diesel engine consumption increases year by year, and refines the petroleum resources exhaustion day by day of diesel oil, and countries in the world are all in the alternative fuel of seeking diesel oil for this reason.Countries in the world generally acknowledge that through development test the coal preparing dimethy ether is the clean fuel that substitutes diesel oil.But during the work of the injector nozzle matching parts of diesel injector, rely on diesel fuel lubricity and sealing between needle-valve and the needle-valve body, (3～8Kg/ms) is little a lot, and needle-valve and needle-valve body be wear out failure, fuel leak soon because the fluid viscosity (0.15Kg/ms) of dimethyl ether is than diesel oil fluid viscosity during the diesel engine dimethyl ether fuel.This problem has hindered dimethyl ether fuel fuel on diesel engine.Someone uses the dimethyl ether fuel that doping improves viscosity on diesel engine, this has not only increased fuel cost, the pollutant emission problem of bringing additive to produce in combustion process again simultaneously.
Summary of the invention
Technical problem to be solved by this invention be when avoiding low fluid viscosity fuel such as above-mentioned diesel engine dimethyl ether fuel oil sprayer injector valve matching part abrasion lost efficacy, the problem of fuel leak, the multifuel diesel oil sprayer of low-viscosity fuels such as a kind of burning dimethyl ether that does not rely on lubricated oil sprayer injector valve of fuel oil and needle-valve body, methyl alcohol, ethanol is provided.
The technological scheme that technical solution problem of the present invention is adopted is that this multifuel diesel oil sprayer comprises needle-valve body, annular oil groove, needle-valve, oil injector body.The oil leab that needle-valve body is provided with annular oil groove and communicates with annular oil groove, oil injector body is provided with horizontal oil leab and the oblique oil leab that is connected with oil leab, and the high-tension lubrication oil pipe is communicated with horizontal oilhole, vertical oilhole on the oil connection bolt, vertical oilhole is communicated with horizontal oil leab, horizontal oil leab is connected with annular oil groove with oil leab connection, oil leab with oblique oil leab connection, oblique oil leab.Diesel engine when work extreme pressure lubricant lubricates needle-valve and needle-valve body and also seals through high-tension lubrication oil pipe, horizontal oilhole, vertical oilhole, horizontal oil leab, tiltedly oil leab, oil leab and annular oil groove enter the gap of needle-valve and needle-valve body.
Beneficial effect of the present invention: 1, improved lubricated between diesel injector needle-valve and the needle-valve body, solved the problem of low-viscosity fuel needle-valve such as diesel engine dimethyl ether fuel and the inefficacy of needle-valve body very quick-wearing; 2, its sealing is improved, the problem of fuel leak in oil-fuel injector needle-valve and the needle-valve body gap when having solved low-viscosity fuels such as diesel engine dimethyl ether fuel in the gap that enters between diesel injector needle-valve and the needle-valve body of extreme pressure lubricant; 3, make diesel engine can dimethyl ether fuel, pluralities of fuel such as methyl alcohol, ethanol.
